Answer: You didn't put any statements lol
Explanation:
But basically natural selection is when organisms with the most favorable traits will survive and reproduce. (ex. there are 2 strains of bacteria - one that resists antibiotics and one that doesn't. The one that resists the antibiotics will strive and reproduce because that will be the more favorable trait that will be able to be inherited by future generations.)
False
-the drag
-the coefficient of friction
-the starting friction
The coefficient of friction
Answer:
Explanation: Cytological markers such as the translocated segment and the chromosome knob play a crucial role in various biological research and applied sciences. These markers have proven to be invaluable tools for understanding genetic diversity, evolution, and gene mapping in organisms. The translocated segment, which is an exchange of genetic material between nonhomologous chromosomes, can provide insights into evolutionary relationships between species. By studying translocations, scientists can determine how different species are related and how genetic material has been exchanged or rearranged during evolution. On the other hand, the chromosome knob is a distinguishing structure found on certain chromosomes that serves as a reliable cytological marker for gene mapping and breeding programs. It facilitates the identification of specific genes associated with particular traits or diseases through cytogenetic techniques. Moreover, these cytological markers enable researchers to develop breeding strategies that aim at improving crops' yield, disease resistance, or other desirable qualities by precisely transferring particular chromosomal segments or genes identified by the presence of knobs and translocations. Hence, understanding the significance of cytological markers is vital for both basic scientific discoveries and practical applications in agriculture and medicine.
Answer:
The given statement is true.
The flowers which contain both male and female reproductive structures are called bisexual flowers.
Stamen refers to the male reproductive part of the flower. It consisted of anther and filament.
Pistil refers to the female reproductive part of a flower. It consisted of stigma, style, and ovary.
So, bisexual flowers are those which contain both stamen and pistil.
For example, Hibiscus, Sunflower, Lily, Rose, Tulip, Daffodil, Mustard, Brinjal, Tomato, et cetera.
